3 BACKGROUND In the past 3 years the role of the Advanced Practice Nurse (APN) has evolved more than any other healthcare professional. Today, in many states, APNs can practice independently as a primary healthcare provider. However, with this greater autonomy comes greater accountability. In 24, Nurses Service Organization (NSO), in collaboration with CNA, released the first ever report analyzing professional liability claims brought against Advanced Practice Nurses. This current study was conducted to update the information acquired in the 24 study and was expanded to provide greater insight and additional risk management recommendations to assist APNs identify and minimize risk exposures. KRC () was contracted to conduct this study on behalf of AON s Affinity Insurance Services division. OBJECTIVES 1. To identify the high risk areas and other APN practice conditions that may have contributed to an incident by comparing the data gathered from APNs who have not had a claim against APNs who have been identified by CNA and NSO as having a claim incident. 2. To learn what differences, if any, exist between the demographics of APNs with claims and those without claims, including but not limited to primary state and location of practice, gender, age, etc. 3. To investigate the specialty areas and practice settings of APNs with claims and those without claims and to understand the relationship, if any, between the APN s practice setting and likelihood of a claim. 4. To determine the APN s perception of the causes of a professional liability incident. 5. To better understand the educational and clinical preparation for advanced practice nursing and to ascertain if there are any educational differences that may have left APNs with claims unprepared for their clinical practice. 6. To explore the relationships between claim severity and the demographics, educational preparation, practice settings, experience and other data elements collected in the online survey of APNs seeking to identify the potential predictors of claim severity. 3

4 METHODOLOGY The primary focus of this study was to compare and contrast the demographics, educational preparation and practice conditions of APNs who have had a claim with those who have not had a claim. In order to facilitate comparison and contrast between the claim and non-claim APNs, the questionnaires were designed with parallel questions appropriately asked of each segment. All NSO actively insured Advanced Practice Nurses were eligible to participate in this study of professional liability claims against APNs. Of the nearly 24, APNs invited to participate in the study, 1,38 were identified as having a professional liability claim filed with NSO/CNA in the past five years. In addition to active insured APNs, the sample included APNs who dropped their NSO policies if they had an incident in the past five years. On June 23, 29, an internet survey was launched. APNs with an address on file were sent an invitation from NSO to participate in the survey. APNs without an address on file as well all bounce backs were sent postcard invitations from NSO on June 29, 29 or June 3, 29 directing them to the NSO website to participate in the survey. All respondents were given a reference ID that was used to track their response. A $1, drawing was promoted as a premium incentive to help lift the survey response rate. Two follow-up reminder s were sent to non-claim APNs and three follow-up reminder s were sent to APNs with a claim. The deadline for the survey and drawing for the non-claim group was July 13, 29. Because of the sensitive nature of the survey, an additional snail mail letter was sent to claim non-respondents on July 17, 29 to assure the APNs of confidentiality and encourage those who did not think they had an incident to participate. The deadline for the claim group was extended to July 27, 29 to allow for responses to the third reminder and snail mail invitation. Survey responses were collected until July 28, 29. 4

5 RESPONSE RATE Completed questionnaires were checked and edited for response clarity. For non-claim respondents a qualified completed survey required input for all questions up to, but not including the demographic questions (age, gender, highest educational degree earned and location of practice). Our sample included fewer APNs with claims. Finding value in the open-ended responses given by APNs with claims, even when the survey was otherwise incomplete, we decided to preserve as many claim respondents as possible. The criteria for a claim complete was therefore loosened to include all except duplicate responses and totally incomplete surveys. A total of 3,354 responses were received. 317 returns were disqualified because of duplication or incompleteness. 3,37 respondent surveys - 2,75 non-claim and 287 claim surveys - were tabulated and used for the initial report which was based solely upon incidence of claims as originally defined by CNA. This updated report takes a deeper dive into the data, readdressing the definition of claims to include only those which currently had a significant reserve (more than just a few dollars) or that actually resulted in a payment (indemnity and/or expense). 135 claims closed with no payment and pending or open claims with no significant reserve were eliminated from the analysis. 152 claim surveys were used for this second phase of the analysis.

6 INTERPRETATION OF RESULTS Results of a survey based on a sample chosen from a population of interest do not yield exact information about the population. Instead, the results represent estimates of the actual situation. The difference between the estimate and the actual figure is the statistical error or uncertainty. For any given level of confidence, the statistical uncertainty associated with any particular survey result varies according to both the size of the sample (or subsample) upon which the statistic is based and the actual estimate itself. Many of the statistical comparisons were made using the Chi-Square statistic. This non-parametric procedure allows for the efficient analysis of frequency type data. By this method, actual (un-weighted) data collected ( observed ) are numerically compared to what would be likely or expected. In conducting the Chi-Square analysis for this report, data from several categories were often collapsed, resulting in a 2 x 2 data matrix. It was upon this matrix that the statistical test was performed. In this case, the typical analysis consisted of number of cases (the frequency ) reported in a given category. Again, the.5 level of significance was applied. For nominal data, the statistical comparisons were made using the mean. The mean is a particularly informative measure of the "central tendency" of the variable if it is reported along with its confidence intervals. We are interested in statistics (such as the mean) from our sample only to the extent to which they can infer information about the population. The confidence intervals for the mean give us a range of values around the mean where we expect the "true" (population) mean is located (with a given level of certainty). Note that the width of the confidence interval depends on the sample size and on the variation of data values. The larger the sample size, the more reliable is its mean. The larger the variation, the less reliable is the mean. In marketing, like other social sciences, the general guideline is to use a 95% (alpha=.5) confidence level as the basis for estimating statistical error and the significance of differences between two or more statistical results. This means that we would expect re-administration of the survey with equivalent samples to yield substantially different results (thus suggesting different conclusions) no more than five times in one hundred. If you set alpha to a smaller value, then the interval would become wider thereby increasing the "certainty" of the estimate. These considerations should be taken into account when interpreting the results of this or any other statistical study. Consequently, when discussing the results, the text of this report will refer to difference in means in a definitive manner only if the probability of finding inconsistent results when re-administering the survey is less than five percent (i.e., p<.5). 6

7 Regression analyses were conducted in an attempt to identify potential predictors of APN liability claims. Linear regression is used to model the value of a dependent scale variable based on its linear relationship to one or more predictors. A multiple linear regression analysis was used to attempt to model the relationship between the dependent variable, severity ($$ amount of paid or reserved claims) against multiple independent predictor variables in the data. The severity of claims is a continuous variable and a linear or straight line relationship is assumed to exist between the dependent and independent variables. Independent variables that were categorical variables were recoded to binary (dummy) variables prior to modeling. For each value of the independent variable, the distribution of the dependent variable must be normal. The variance of the distribution of the dependent variable is assumed to be constant for all values of the independent variable. The relationship between the dependent variable and each independent variable should be linear, and all observations are assumed to be independent. Scatterplots of each independent variable against the dependent variable were examined checking for linearity, heteroscedascity, outliers and strength of the relationship to determine appropriateness in the model. Binary logistic regression was used to attempt to identify potential predictors of the dependent variable, having a claim or not having a claim. While linear regression can be quite powerful and useful for continuous variables, it is not suitable for predicting the relationship when the dependent variable is a dichotomous categorical variable. Since the dependent variable, Claim, has only two values, i.e. not having a claim, No = and having a claim, Yes = 1, the probability of an event must lie between and 1. It is impractical to model probabilities with linear regression techniques, because the linear regression model allows the dependent variable to take values greater than 1 or less than. The logistic regression model is a type of generalized linear model that extends the linear regression model by linking the range of real numbers to the -1 range. The binary discrete output is converted into continuous output by calculating the probability for the occurrence of a specific event. The procedure for modeling a logistic model is determining the actual percentages for an event as a function of the independent predictor variables and finding the best constant and coefficients fitting the different percentages. For both linear regression and logistic regression models, a p-value is calculated for each coefficient. If the p-value is low then there is a significant relationship between the independent variable and the dependent variable. "Goodness-of-fit" tests are conducted to see whether the model adequately fits the actual situation. Low p-values indicate a significant difference of the model from the observed data. Hence, the p-values should be above.5 to show that there are no significant differences between the predicted probabilities (from the model) and the observed probabilities (from the raw data). 7

8 SCOPE & LIMITATION This report is an extension of the previous reporting of the 29 APN survey. While the previous analysis was limited to the questions asked of the APNs in the online survey, this analysis incorporates the actual claim data matched to survey respondents. The data were examined by segments, specifically comparing and contrasting claim respondents vs. non-claim respondents. This analysis is limited to claims with payment only. For the purposes of this report, we have dropped APNs with claims if the claim was closed with no payment or is pending or open with a reserve of $3 or less. The net effect is a dataset of 152 APNs who had a paid claim (indemnity and/or expense) or have a pending open claim with a significant reserve as provided by CNA data. These 152 APNs with claims were compared to the 2,75 APNs without claims in an attempt to identify potential predictors of APN liability claims. The previous analysis was based on 287 APNs. With the deletion of 135 APNs who had a claim closed with no payment, it is expected that the details, outcome and projections about the APN claim data would be different from the previous results and may even appear to be contradictory to those stated in the previous report. Where contradictory information is being reported, this current report is considered to be more reliable. The predictor variables in the regression models are all significantly related to the outcome variables of incidence or total paid claims/reserved. While this indicates that there is a relationship between the predictors and the outcome event, it cannot be assumed that the predictors cause the outcome event. It is also important to note that while each of the predictors are significant, there is generally an overlap and predictors are only added to the models if they can add a unique contribution. Two or more predictive variables may explain the same variation in the outcome of incidence or severity. Therefore if these same models were built with variables removed or added, the unique contribution of the current set of predictors would be expected to change. Because the data are limited to APNs insured by CNA professional liability through NSO, the reader is cautioned from projecting these results to the entire population of APNs which would include uninsured APNs and APNs insured in other nurse practitioner professional liability programs. 8

How did you earn your APN designation? Claim (Base=152) Non-claim (Base=2,75) Total (Base=2,92) Community college program Hospital-based program University/college on-site program On-line program None Other (please specify) Few APNs have earned their APN designation through sources other than a university or college on-site program. 88% of all APN respondents maintain that they used a university on-site program to achieve their APN designation. Only 5% of all APNs reached APN status using on-line programs alone. Very few used only hospital based or community college programs. Among the 5% who used other specified sources, most often it was a combination of on-site programs and on-line programs.

Self-employed APNs account for 14% of positions, 1% working full-time and another 4% working part-time. Working as a self-employed APN represents an identified area of potential risk. A significantly greater proportion of APNs who have had a claim are self-employed fulltime (15% v. 1%). $16, $14, $12, $1, $8, $6, $4, $2, $ $8,244 $51,274 $11,773 $85,776 $144,941 $13,716 $79,532 Missing (N=1) Self-employed, Self-employed, full time (N=21) part time (less than 24 hours per week) (N=5) Employed full time (N=96) Employed part time (less than 24 hours per week) (N=18) Other (please specify) (N=2) Total (N=152) Q9.

22 Named in Lawsuit Three-quarters of APNs with claims were named in the lawsuit along with their employer, facility and/or other healthcare professionals 9% of the APNs with claims admit that they were named alone in the lawsuit. 74% of APNs with claims were named along with their employer, facility and/or other healthcare support staff. Q11. Who was named in the lawsuit? (Check one) Claim (Base=142) Do not know, 17% Self and others, 74% Only self, 9% Q12. What others were named in the suit? (Check all that apply) (Claim Base=156) Physician Hospital Facility NP RN Other healthcare support staff In 92% of cases where someone else was named, it was a physician. 22

23 Being named in a lawsuit with others increases APN claim severity by eleven times. When an APN is involved in a suit alone, the average claim dollars are much lower than when APNs are named with others. Knowing that three-quarters of the lawsuits involving APNs named others as well, it is concerning that the average claim losses are 11 times greater for APNs named along with others. $12, $111,498 $1, $8, $79,532 $6, $4, $2, $8,244 $1,62 $7,17 $ Missing (N=1) Only self (N=13) Self and others (N=15) Do not know (N=24) Total (N=152) Q11.

(Check all that apply) Since a physician is named in 92% of the cases where an APN is not named alone, it is not surprising that the average claim severity for APNs named with others is only 4% lower than the $115,733 average claims paid/reserved when a physician is named. 23

24 Being named in a lawsuit with a physician results in claim losses 92% greater than when someone else is named along with the APN It is interesting that when physicians are not named along with the APN (that is when the APN is named with someone other than a physician) the average claim paid/reserved is $6,138, indicating a severity factor of 1.92 times or 92% higher claim losses associated with being named along with a physician compared to being named with others.

26 Percent Years Practicing as an APN Years of experience as an APN can minimize the risk of an incident Q13. (At the time of the incident), how many years have(had) you been an APN? Claim (Base=141) Non-claim (Base=2,75) 41 Total (Base=2,891) Less than 2 years 2 to 5 yrs 6 to 1 yrs 11 to 15 yrs More than 15 During their first two years of practice, many APNs are being mentored and taking on less responsibility in their new role. While no significant differences were found among APN with less than 2 years of experience, it is not surprising that beyond their first two years of practice, increasing years of experience as an APN appears to be a factor in avoiding an incident. APNs are at increased risk of claims until they are sufficiently experienced and have been practicing for approximately 1 years. 76% of APNs with claims were practicing for 2 to 1 years compared to 51% in the non-claim group. 26

27 On average, the APNs with claims had been an APN for 7.6 years at the time of the incident while the average APN without claims has been an APN for 9.7 years.

43 Percent Daily Patient Quotas Daily patient quotas are not associated with claim incidence. APNs with claims were being asked to increase or maintain the daily number of patients seen with less frequency than reported by APNs without claims Q23. (At the time of the incident, were), are you specifically asked to: Claim (Base=137) Non-claim (Base=2,75) 74 Total (Base=2,888) Increase number of patients seen per day Decrease number of patients seen per day Maintain number of patients seen per day Do not know / not applicable 17% of APNs with claims were specifically asked to maintain daily patient quotas and another 9% were asked to increase their daily patient workload at the time of the incident. It is noteworthy that a greater proportion of APNs without claims were specifically asked to maintain (27% v. 17%) or to increase (22% v. 9%) the number of patients being seen per day at their practice, leading us to surmise that increases in patient quotas are not a contributing factor to the incidence of malpractice suits against APNs. Not surprisingly, none of the APNs with claims and less than 1% of the APNs without claims were asked to decrease their patient workload. Perhaps because APNs tend to practice in a more autonomous setting, three-quarters of the APNs with claims and half of the APNs without claims reported that a required increase, decrease or maintenance of patients seen per day was not applicable to them or they did not know if there were daily patient quotas at their practice. $14, $12, $1, $8, $6, $4, $2, $ $1,59 Missing (N=15) $54,753 Increase number of patients seen per day (N=12) $118,561 Maintain number of patients seen per day (N=23) 43 $83,797 $79,532 Do not know / not applicable (N=12) Q23.

44 Percent Overtime While 11% of APNs with claims were required by their facility to work overtime at the time of the incident, this does not appear to be a contributing factor to the incidence of malpractice suits against APNs Q24.(At the time of the incident, did), does your facility require you to work overtime? Claim (Base=137) Non-claim (Base=2,75) Total (Base=2,887) No Yes Among both APNs with claims and those without, the vast majority say they are not required by their facility to work overtime. From verbatim comments provided, it is evident that APNs can work in a salaried postion that does not exactly require overtime, but may have them putting in 5 hours per week or more in order to do their job thoroughly and completely. At the time of the incident, 11% of the APNs with claims say they were required to work overtime. This is not significantly different from the 17% of APNs without claims who acknowledged having overtime requirements at their facilities. $14, $12, $1, $8, $6, $82,972 $12,58 $79,532 $4, $2, $ $1,59 Missing (N=15) No (N=122) Yes (N=15) Total (N=152) Q24.(At the time of the incident, did), does your facility require you to work overtime? 44

Do you perceive that inadequate staffing levels at the facility contributed to the cause of the incident? (Claim Base=137) No, 88% Yes, 12% While 12% of APNs with claims perceive that inadequate staffing at their facility at the time of the incident may have been a contributing factor, the majority (88%) of APNs with claims do not believe that inadequate staffing levels at their facility was in any way responsible for causing the incident. $1, $9, $8, $7, $6, $5, $4, $3, $2, $1, $ $88,67 $8,187 $79,532 $1,59 Missing (N=15) Yes (N=17) No (N=12) Total (N=152) Q25.

48 Claim Incidence Risk Factors Model In an effort to identify potential predictors of APN liability, 152 APN with claims were compared to the 2,75 APNs without claims who completed the internet survey. So that the importance of this latter segment would not be over-inflated in the comparison, the 2,75 APNs without claims were weighted to create a representative segment of 152 APNs without claims. Binary logistic regression analysis was conducted on the data, describing the effects of each independent predictor variable on the severity of claims variable, while controlling for the other covariates in the model. All possible ordering and groupings of independent variables were evaluated to determine which combinations produced the most effective models. The models were built by sequentially adding variables to the analysis, evaluating the sensitivity of the model and examining the model 2LogLikelihood scores and Chi-square p-values calculated for each independent variable. Independent variables that did not increase model effectiveness were discarded. The predictor variables determined to have a relationship with the outcome variable are certification area, practice area, being specifically asked to increase or maintain the number of patient seen per day and use of electronic medical records.

49 All categorical variables were converted to dichotomous variables for this analysis and have been assigned a parameter code of or 1, indicating it is false or true respectively. Notice that some variables in the table below have been inverted in the parameter coding. For example, q27.13 is true for APNs who do NOT use electronic medical records or a combination of electronic/handwritten medical records. This inversion was done to make the model easier to interpret by keeping outcome relationships consistently in the positive direction. q3.2 Family practice certified q23.13 NOT Increase OR Maintain number of patients seen per day q Phys Office OR Nursing home OR Prison q NOT Community clinic OR school/college clinic q27.13 NOT Electronic OR combination of electronic and handwritten Categorical Variables Codings Parameter coding Frequency (1) The results of the binary logistic regression model results yielded the equation: Predicted Claims Paid/Reserved = (Q3.2) (Q ) +.62 (Q ) (Q23.1.3) (Q27.1.3) The fit of the model is very good, accurately predicting 73.1% of the combined observed responses and accurately predicting 79.6% of the claims correctly.

The cut value is.5 Predicted Claim Paid/Reserved Percentage No Yes Correct No Yes Hosmer and Lemeshow Test Step Chi-square df Sig A well-fitting model is confirmed by the Hosmer and Lemeshow test statistic =.995, much greater than.5, indicating that the observed values are not significantly different from the model predicted values. The overall model was significant with a Chi-Square p-value of less than.1. All of the explanatory variables related to APN liability claims are statistically significant at the five percent level. 49

Variable(s) entered on step 1: q27.13, q23.13, q , q , q3.2. In the Variables in the Equation table, the Exp (B) column represents the odds ratio. The odds ratio for Q27.13 (Not utilizing EMR or combo) is Exp (1.693) = This tells us that, holding all the other predictors fixed, the odds for a claim paid or reserved are times greater when APN practices are NOT utilizing electronic medical records or combo than in APN practices using electronic medical records or a combination of EMR and handwritten records. In terms of percent change, the odds for APNs NOT utilizing EMR or combo are 444% higher than APNs utilizing EMR or combo. The lack of utilization of Electronic medical records or a combination of EMR and handwritten records is the most significant factor associated with the incidence of APN liability claims. APNs certified or licensed in family practice (Q3.2) are times more likely to have a claim than APNs with other certifications. Practicing in a physician s office, nursing home or prison (Q3.8.1) increases the odds of having a claim by a factor of while NOT practicing in a community clinic & health center or school/college clinic ( ) increases the odds by a factor of times more than APNs in the remaining practicing settings. Not totally surprising because it was also observed in the actual data, the final somewhat inapt predictor forecasts the odds of an APN claim being nearly 3 times greater when NOT asked to increase or maintain the number of patients seen daily (Q23.13). 5

51 Severity Risk Factors Model While the previous model identified potential predictors of APN claim incidence, we are also interested in identifying the predictors related to the increasing size of the claim payments and reserves. This second model attempts to predict the risk factors associated with likelihood to have an incident resulting in high expenses, indemnity or reserves. Using the data collected from 152 APN claim survey respondents, a linear regression analysis was conducted to identify the probable predictors of claim severity. Examining the total dollars of claims paid and reserved revealed that it was a skewed distribution, which violates the assumption of normality. A log transformation of the values was conducted to normalize the distribution. Explanatory variables were selected using several different methods, forward, stepwise and backward removal in order to determine combinations which produced the most effective models. Independent variables that did not increase model effectiveness were discarded. Each of the explanatory variables 51
