Evaluation of primary non-compliance with discharge medication at a private hospital

Kruger, Daniel Frederik January 2009 (has links)
Thesis (MSc. (Med.)(Pharmacy))--University of Limpopo, 2009. / ABSTRACT Background: When a patient is discharged from the hospital, the doctor may prescribe medication to be used at home which is called TTO (To Take Out) medication. Failure by the patient to collect TTO medication might be intentional or may indicate a lack of appropriate structures and procedures at the hospital to provide such care on discharge, and/or failure by the health care professionals to reach concordance with the patient to ensure that he/she continues to take medications as prescribed. Objectives: The purposes of this study were to examine the prevalence of primary non-compliance with medication in this private hospital and to explore its association with various factors contributing to its existence. Methodology: The study was conducted at a private hospital in Gauteng, South Africa. The study focused on discharged patients who did not redeem their TTO medication. Thus only patients discharged from the hospital within a thirty day period between 25 May 2009 and 23 June 2009 were included in the study. For each subject the discharge medication prescription was reviewed and the following determined: number of items prescribed, number of items dispensed at the hospital pharmacy, whether any items were non-dispensed, whether any items were partially dispensed and reason for any item non-dispensed or partially dispensed. A telephone call was made to those subjects for whom a discharge medication script was prescribed, but no medication was dispensed at discharge. Information was collected from the patients to identify possible reasons for not redeeming discharge medication. Results: In total 1365 records were evaluated. TTO medication was prescribed for 1161 (85%) patients discharged. All items were redeemed in full by 854 (74%) of the patients, 118 (10%) patients redeemed no discharge medication, 101 (9%) patients redeemed only some items prescribed, 74 (6%) patients redeemed all items partly, 14 (1%) patients redeemed some items partly and some not at all and for seven v patients details were not known. Four reasons and five types of medication together accounted for 54% of the total value not redeemed. The four reasons include the following: medical aid TTO rules, patient unaware of TTO being prescribed, ward stock given, patient still had stock at home, and the types of medication included: blood and haematopoietic agents, analgesics, antimicrobials, agents of the gastrointestinal tract and unclassified. Conclusion: Some patients reported that they took own decision not to redeem the medication and some still had stock at home, a fact that should lead healthcare providers to ensure that they reach concordance with their patients.

Post-fire regeneration and survival of whitebark pine (Pinus albicaulis)

Moody, Randall 11 1900 (has links)
The recruitment trends of whitebark pine (Pinus albicaulis Engel.) were investigated in 18 recently burned stands in the Canadian Rockies and the North Cascades. Whitebark pine recruitment in recently burned stands (fires < 60 years prior) was compared to that on paired control stands (no recent fire) to determine if fire was necessary for successful recruitment. Recruitment in recently burned stands was compared with ecological and seed source variables. Along a chronosequence, whitebark pine recruitment was compared with precipitation and with Pacific Decadal Oscillation (PDO). Field sampling consisted of systematic plots established in sampling grids in both burned and control stands. In each plot ecological data was collected as was data regarding whitebark pine age, height, and disease status. Recent fire was not found to be a requirement for recruitment. Both distance to and size of seed source were important predictors of whitebark pine recruitment. Whitebark pine regeneration densities were low on warm steep rocky sites. High whitebark pine recruitment on cooler aspects suggested that whitebark pine could establish on cooler sites when competition was removed by fire. Most stands were composed of mixed conifers, but only lodgepole pine appeared to limit the growth of whitebark pine. Whitebark pine recruitment was episodic on all stands, and recruitment years were correlated among many stands separated by large distances. Episodic recruitment may be due to more than cone masting as recruitment in several stands was also correlated with growing season precipitation and positive PDO values, which may increase the length of growing season. A logistic regression model suggested that infection by white pine blister rust is most likely on older seedlings. The percentage of whitebark pine trees infected by white pine blister rust on a site increased with time since fire. Prescribed fires and wildfires should address retention of whitebark pine seed trees on site. Fires that remove competition from mesic-submesic stands may result in the most rapid recruitment of whitebark pine. With the exception of stands heavily stocked with lodgepole pine, all recently burned stands in this study would benefit from increased stocking of whitebark pine by planting.

Landowners' perceptions on the use of prescribed fire as a management tool

Woodard, Justin Bradley 25 April 2007 (has links)
The purpose of this project is to determine landowners’ perceptions on the use of prescribed fire as a management tool. The majority of Texas rangelands are privately owned, and the sustainable management of almost all of the state’s rangelands is contingent upon private land management decisions. Therefore, it is imperative for policy makers and extension agencies to understand landowners’ perceptions, interests and concerns about alternative land management techniques. This is especially important for the use of prescribed fire, which has been identified as a critical management tool for maintaining the productivity of most Texas rangelands yet many landowners do not include it as an integral practice in managing their land. A better understanding of landowners’ perspective of the use of fire could facilitate the increased use of this management tool through the development of effective educational, costshare and fire planning programs. The study reported here consisted of a mail survey of all 185 members of the Edwards Plateau Prescribed Burn Association (EPPBA) and 600 landowners in six counties in Texas. Four of those counties were located in the Edwards Plateau (Sutton, Schleicher, Mason, Llano) and two counties were located in the Rolling Plains (Throckmorton, Shackleford). In each county, 100 landowners possessing at least 50 acres of land were randomly selected for inclusion in the survey. The mail survey approach followed Dilman’s five-step mailing procedure. Fire is an important rangeland management tool, but in a state where the majority of the land is privately owned fire suppression is still a dominant perspective. Our study suggests that important efforts to increase the use of prescribed fire include, educational programs about use of fire by landowners, increased assistance with prescribed fire plans, cost-sharing programs for fire implementation, and reduction in the legal liability associated with fire that burns out of control. Encouraging agencies to back educational programs and help teach landowners about the effects and uses of fire (burn plan assistance), and developing a resource pool to underwrite fire policies could increase the interest in and risk associated with the use of prescribed fires to more effectively manage rangelands in Texas, and elsewhere.
